Characterisation of dark matter in direct detection experiments: Singlino versus Higgsino
Hiçyılmaz, Yaşar (Elsevier, 2021)We show how the material used in direct detection experiments of Dark Matter (DM), in the presence of a signal of it, can afford one with the possibility of extracting the nature of the underlying candidate. We do so for ... -
Charged Higgs boson in MSSM and beyond
Hiçyılmaz, Yaşar; Selbuz, Levent; Un, Cem Salih (Amer Physical Soc, 2018)We conduct a numerical study over the constrained MSSM (CMSSM), next-to-MSSM (NMSSM) and U(1) extended MSSM (UMSSM) to probe the allowed mass ranges of the charged Higgs boson and its dominant decay patterns, which might ... -
E6 motivated UMSSM confronts experimental data
Frank, Mariana; Hiçyılmaz, Yaşar; Moretti, Stefano; Özdal, Özer (Springer, 2020)We test E-6 realisations of a generic U(1)' extended Minimal Supersymmetric Standard Model (UMSSM), parametrised in terms of the mixing angle pertaining to the new U(1)' sector, theta(E6), against all currently available ... -
Efektif U(1)' modellerinde doğallığın incelenmesi
Hiçyılmaz, Yaşar (Balıkesir Üniversitesi Fen Bilimleri Enstitüsü, 2012)U(1)' modeli standart model sonrası süpersimetrik modellerin en etkililerinden biridir. Bu modele göre doğada ekstra bir elektro-zayıf ayar simetrisi vardır. Bundan dolayı bu modelin parçacık spektrumunda MSSM'e ek olarak ... -
Electron and muon magnetic moments and implications for dark matter and model characterisation in non-universal U(1)' supersymmetric models
Frank, Mariana; Hiçyılmaz, Yaşar; Mondal, Subhadeep; Özdal, Özer; Ün, Cem Salih (Springer, 2021)We attribute deviations of the muon and electron magnetic moments from the theoretical predictions to the presence of an additional U(1)' supersymmetric model. We interpret the discrepancies between the muon and electron ... -
Family non-universal U (1)' model with minimal number of exotics
Hiçyılmaz, Yaşar; Moretti, Stefano; Solmaz, Levent (Elsevier, 2021)dsf -
Flavour non-universal UMSSM with minimal number of exotics
Hiçyılmaz, Yaşar; Moretti, Stefano; Solmaz, Levent (CERN, 2021)We report the phenomenological implications of several family non-universal U(1)′ sub-models in the U(1)′-extended Minimal Supersysmmetric Standard Model (UMSSM) possesing an extra down quark type exotic field. In doing ... -
Least fine-tuned U(1) extended SSM
Hiçyılmaz, Yaşar; Solmaz, Levent; Tanyıldızı, Şükrü Hanif (Elsevier Science, 2018)We consider the Higgs boson mass in a class of the UMSSM models in which the MSSM gauge group is extended by an additional U(1)' group. Implementing the universal boundary condition at the GUT scale we target phenomenologically ... -
Leptophobic Z ' bosons in the secluded UMSSM
Frank, Mariana; Hiçyılmaz, Yaşar; Moretti, Stefano; Özdal, Özer (Amer Physical Soc, 2020)We perform a comprehensive analysis of the secluded supersymmetric U(1)' model, consistent with present experimental constraints. We find that, in this model, the additional Z' gauge boson can be leptophobic without resorting ... -
Light Z′ signatures at the LHC
Hiçyılmaz, Yaşar; Khalil, Shaaban; Moretti, Stefano (American Physical Society, 2023)In this work, we discuss a distinctive pp -> Higgs -> Z'Z' -> 4l (l = e, mu) signal at the LHC, where the "Higgs" label refers to the Standard Model-like Higgs state discovered in 2012 or a lighter one in the framework of ... -
Model characterization and dark matter in the secluded U(1)' model
Hiçyılmaz, Yaşar; Selbuz, Levent; Solmaz, Levent; Un, Cem Salih (Amer Physical Soc, 2022)We consider a class of U(1)'-extended minimal supersymmetric extension of the Standard Model (MSSM) in which the U(1)' symmetry is broken by vacuum expectation values of four MSSM singlet fields. While one MSSM singlet ... -
Monophoton events with light Higgs bosons in the secluded UMSSM
Hiçyılmaz, Yaşar; Selbuz, Levent; Ün, Cem Salih (American Physical Society, 2023)We explore the Higgs boson implications of a class of supersymmetric models, which extends the MSSM gauge group by a U(1)' symmetry, which is broken at low energy scales by vacuum expectation values of four MSSM singlet ... -
Muon anomalous magnetic moment constraints on supersymmetric u(1)' models
Cincioğlu, Elif; Kırca, Zerrin; Sert, Hale; Solmaz, Saime; Solmaz, Levent; Hiçyılmaz, Yaşar (Amer Physical Soc, 2010)We study the anomalous magnetic moment of the muon in supersymmetric E-6 models and generic U(1)' models to probe the model reactions and to find constraints on the large parameter space of these models. For future searches, ... -
Quasi-Yukawa unification and fine-tuning in U(1) extended SSM
Hiçyılmaz, Yaşar; Ceylan, Meltem; Altaş, Aslı; Solmaz, Levent; Ün, Cem Salih (American Physical Society, 2016)We consider the low scale implications in the U(1)' extended minimal supersymmetric Standard Model (UMSSM). We restrict the parameter space such that the lightest supersymmetric particle (LSP) is always the lightest ... -
Son deneysel veriler ışığında CMSSM
Hiçyılmaz, Yaşar (2021)Bu çalışmada Büyük Hadron Çarpıştırıcısı (BHÇ) ve karanlık madde sonuçları çerçevesinde, son deneysel veriler kullanılarak sınırlandırılmış Minimal Süpersimetrik Standart Model (CMSSM)'in durumu incelenmiş ve parametre ... -
t - b - tau Yukawa unification in non-holomorphic MSSM
Hiçyılmaz, Yaşar (Springer, 2021)We show that in the CMSSM with the non-holomorphic soft SUSY breaking terms, the Yukawa coupling unification of the third family fermions at the GUT scale, called t - b - tau Yukawa unification (YU), is possible under the ... -
Yüksek halka mertebelerinde standart model Higgs sektörünün yoklanması
Hiçyılmaz, Yaşar (Balıkesir Üniversitesi Fen Bilimleri Enstitüsü, 2017)Bu tezde temel amacımız Standart Model’in Higgs sektörünün yüksek halka mertebelerinde yoklanmasıdır. Literatürde dört halka mertebesine kadar hesaplanmış olan Higgs'in efektif potansiyeliden türetilecek Higgs'in öz bağlaşım ...
